All current monographs on Australian law and legal system are on Level 2, as part of a sequence arranged initially by legal subject/topic rather than jurisdiction. Books in this subject sequence all have shelf marks beginning K.
(Those books which continue to have shelf marks in the range Cw Aus 450 to Cw Aus 510 are in the secondary collection of superseded monographs on the Ground Floor. They are freely accessible (via stairs or lift) to anyone who needs to consult them.)
Australian commentary in the K (or Moys) classification sequence
The following is an overview of the principal sections in the K sequence - with examples of Australian treatments of the subjects.
As the examples show, not all such works have "of Australian" or "Australian" etc in their titles. The shelf mark itself can help you identify works on Australian law - in many sections look out for A8 or AUS in the third line.
KB Biography, Memoirs, "popular" accounts of trials
KB.15.AUS.GAU 2010 From Moree to Mabo : the Mary Gaudron Story
KC Domestic law with international dimension
eg KC.214.AUS.AUG 1995 Extradition : Australian Law and Procedure
KL Legal System, Administration of Justice
KL.26 is just for books on the Australian legal system
eg KL.26.APP 2014 is Australian Public Law
KL.176 Australian (federal level)
KL.177 plus three letter State code for individual states/territories
In most of the other KL shelf marks, A8 in the third line identifies an Australian-focused work.
KL.251.A8.APP 2016 The Role of the Solicitor-General : Negotiating Law, Politics and the Public Interest
KM Public Law
A8 in the third line of the shelf mark indicates a work looking at the Australian handling of the public law topic.
eg KM.335.A8.BAR 2017 Foundations of Taxation Law
KN Private Law
A8 in the third line of the shelf mark indicates a work about the Australian handling of a private law topic.
eg KN.170.A8.SLA 2014 Family law made simple : marriage, divorce, children, separation & the legal system
